The geological interpretation of side‐scan sonar
Reviews of Geophysics, 1990Recent developments in side‐scan sonar technology have increased the potential for fundamental changes in our understanding of ocean basins. Developed in the late 1960s, “side looking” sonars have been widely used for the last two decades to obtain qualitative estimates of the acoustic properties of the materials of the seafloor. Modern developments in

The Journal of the Acoustical Society of America, 1992
This discloses an improved side-scan sonar capable of locating objects on e ocean floor including the strip directly beneath the sonar transmitter and receiver, which in prior arrangements had to be obtained by another pass. The arrangement includes a platform having acoustic transmitters spaced apart a substantial distance on either side of acoustic ...

Side scan sonar acoustic variability
OCEANS '88. 'A Partnership of Marine Interests'. Proceedings, 2003The authors report the results of research on the inherent variability of side-scan sonar imagery to determine the magnitude and nature of image intensity fluctuations. Two experiments are presented in which a Klein 100-kHz system is operated under controlled conditions that remove all but purely instrumental and acoustic causes of image variability ...

Side-scan sonar image matching
IEEE Journal of Oceanic Engineering, 1998This paper presents a method for the matching of underwater images acquired with acoustic sensors. As a final objective, the system aims at matching data from two-dimensional scenes. The proposed approach carries out a hypothetical reasoning based on objects, represented by shadows and echoes in the sonar images, and their available features.
